unidirectional cylinder are widely used in Finland，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed unidirectional cylinder for customers from Finland.

Introduction to unidirectional cylinder:

If air enters the hydraulic system, the unidirectional cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

When the hydraulic oil is not pumped into the unidirectional cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the unidirectional cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

unidirectional cylinder and hydraulic station selection: Select the type and structure of the unidirectional cylinder according to the operation requirements of the main engine. According to the external load force borne by the unidirectional cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the unidirectional cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the unidirectional cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the unidirectional cylinder, the diameter of the piston and the piston rod.

When the piston speed of the unidirectional cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the unidirectional cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

Answers to some questions about unidirectional cylinder:

Does the abbreviation bc stand for bucket cylinder or boom cylinder?
Hydraulic excavator hydraulic cylinder includes boom cylinder, bucket rod cylinder and bucket cylinder three parts, four cylinders. Because of the different naming conventions of major manufacturers, the meaning of BC is also different, for the sake of insurance, you need to consult the manufacturer.

When the hydraulic cylinder changes from fast to slow, how can the slow speed become more even and the speed can be adjusted?
Reversing valve set 2 reversing valves. The back of one valve goes directly to the cylinder, running at full speed for fast action. Add a speed control valve behind the other valve, and then connect to the cylinder to achieve slow action, you can adjust the opening of the speed control valve, to achieve the speed of the cylinder can be adjusted. An import speed control valve to more than 1,000 yuan, if you think it is too expensive, you can also use the throttle valve instead. However, the throttle valve is greatly affected by the load change.
